Nintendo, Pokemon sue Palworld developer Pocketpair for patent infringement

Nintendo Co. filed a patent infringement lawsuit against Tokyo-based Pocketpair Inc., the maker of hit game Palworld, seeking an injunction and compensation for damages.

The case, brought together with affiliate Pokémon Co., was submitted to the Tokyo District Court on Wednesday, Nintendo said in a statement the following day. Nintendo did not detail which patents it believed were infringed by the game, nor the scale of the relief it seeks.

Palworld was an instant success upon its debut in January, raising the profile of its creator Pocketpair and earning the moniker “Pokémon with guns” among fans, who saw similarities between the fantastical monsters in the game and those in Nintendo’s famed franchise. Patent protection in software typically covers elements of the user experience — rather than the look of characters — and Nintendo may have found gameplay mechanics that it believes infringe on its rights.

“Nintendo filing this lawsuit for patent infringement, not copyright violation, means it has given up making the case that Palworld’s characters are similar to Pokémon’s,” said Toyo Securities analyst Hideki Yasuda. “But it shows Nintendo has more ways to stop games it doesn’t like. The company owns a lot of patents related to basic game mechanics that are used in many titles available today.”

The lawsuit came as a surprise after Nintendo and Pokémon Co. had remained largely silent on the issue for months, though Pokémon Co. had warned that it hasn’t approved any use of its IP for Palworld and would take action if necessary. The game got full-fledged support from Microsoft Corp. in its initial distribution and Pocketpair also teamed up with Sony Group Corp. to sell related merchandise. Pocketpair did not respond to a request for comment.

A representative of Sony Music Entertainment Inc., which set up the Pocketpair collaboration, said in an e-mailed statement that the company is not in a position to issue a comment.

“Nintendo will continue to take necessary actions against any infringement of its intellectual property rights including the Nintendo brand itself, to protect the intellectual properties it has worked hard to establish over the years,” the company said in its statement.
